To all whom, 1,15 may concern/.n 'l

Be it known that I, 'MAX F. W. PLIsKE, a

j citizen of the United. States, residing `at Lakewood, inthe county of'Cuyahoga and State of Ohio, have inventednew and useful Improvements .in Heaters, ofwhich the followingfis a specification;

My mvention relates to.' heating` systems for automobiles andother vehicles; and the object is to .provide a construction of this class by. which the maineXhaust-from' the u engine is utilized as the heating medium;

mobile. with itsgrating removed. v Fig. 3 is a ver- Anotherobject is to rovide means whereby' y andfquickly turned Aonor off, provision being made that none of l the heat may be eas the' foul products of combustionshall leak '.intofthe car.

VAtical-section ofthe heater. v Fig. 4 is a detail ordinary tvp .5o4 This valve-chamber 13 is preferably squared' in perspective.

1 indicates the main exhaust-pipe, leading from the 3 is the inlet-pipe, leading from the exhaust 1 to the heater 4and 5 is an outlet v'pipe leading from the heater 4 tothe murlierv 2, `as

shown.` The heater 4 I have ,shown as square in shape and is composed of the outer andinner casings Gand 7, of'galvanized tin or other suitable material, having between them a layer of asbestos 7 a in order to insure l a iireproof construction and also to'. hold the he'atwithin said heater-box.

' e 8 represents aseries of heating-coils within l the heater 4,.and` 9 isla" grating-coverfor said heater, fitting down flush with the liofor` .4'5

Shanks :extending 'I adapted to telesco e into the shank The' Shanks .16 an 17 are provided' with slots 18 and 19, respectively, registering be-V tween themselves to form a Vsingle .slot,

through which. the valve-rod 20 is adapted to project and be 'held from coming out yby means ofthe nuts 21 and 22l thereon.

23'is 'al stuiiing-boxhaving therein 'the packing 24'tosecure against leakage from the valve-chamber, and 25 is a cap attached tosaid stuiiing-box b f screws 26 and valve-rod 20 reciprocates to fopen :and close the valve. K

27 is a spiral spring held about the Shanks 16 and 17. and operating to hold the disks 14 PI'O" vided with a central s ot, through which the and 15 rmly upon their seats vat all times.

Midway between the inletipe 3- and the outlet-pipe 5,- through the wa l of the heater 4,`

'are arranged the slots 2.8, and opposite said slots vonthe inside vof said wall are .rotatably mountedthe blades 29 on the pin 30, the said lblades 'being adapted to register with4 the said slots 28. r

31 is 'a foot-*lever ivotally mounted on the pin to the rear o the blades 29 and con-y nected to said blades by means of the pin 32. `33 and 34 are connnecting-rods pivotally connected at one end to the free end tof the` valve-rods20, the rod 33 being'pivotally connected at its other end to the end of the footlever, 31 below the pivot 30 by the pin 35 and the rod 34 'being pivotally connected atits other en dto said lever above pivot 30 by the pin 32, connecting said lever to the blades 429.

The, operation of my ydevice is asfollows:

Taking the heater inthe closed position, to open the same the foot is ap lied to lever31, moving it forwardand simu taneously drawing the valve-disks 14 and .15 of-both inlet and outlet-valve from off their seats, thus alinto thecoils 8 by means'o the back kick or back pressurefol owing each explosion of the engine. Simultaneously with the opemng :of the inlet and outlet valves theblades 29v vlowing thehot exhaust-'va ors to'be forced IDO `will be moved from the slots 28, thus allowing fresh air to enter. the heater to bef heated yt-he coils Sand be 4thrownout throughhe grating 9.

'Should eitherjof the valve-disks leak-when i I the `valve is closedl the pressure thus Created within the valve-chamber vwill force theoppositedisk more irml than ever upon 1tsl seat, and should .both 'sks of the inlet-valye leak the outlet-valve still prevent Va -cir-` l the coils Will become cold in a short time.
